Best Image Size for Instagram Posts, Reels, and Stories in 2026

The 2026 Instagram Dimension Guide

Posting the wrong size on Instagram leads to awkward crops and lower engagement. In 2026, the platform prioritizes vertical content more than ever.

1. Standard Feed Posts

• Portrait (Recommended): 1080 x 1350 pixels (4:5 ratio)
• Square: 1080 x 1080 pixels (1:1 ratio)
• Landscape: 1080 x 566 pixels (1.91:1 ratio)

2. Instagram Stories & Reels

Both Stories and Reels use a 9:16 aspect ratio. The ideal size is 1080 x 1920 pixels. Use our Image Resizer to quickly adapt your photos to this format.

Why Your Images Look Blurry

If you upload an image larger than 1080px wide, Instagram will compress it. If it's smaller, they will stretch it. Both result in quality loss. Always resize exactly to 1080px wide before uploading.
